Ard Biesheuvel 6657674b23 crypto: sha3-generic - export init/update/final routines
To allow accelerated implementations to fall back to the generic
routines, e.g., in contexts where a SIMD based implementation is
not allowed to run, expose the generic SHA3 init/update/final
routines to other modules.
